Arizona centaury, rosita
Southeast California, across to south New Mexico, west Texas and a small part of Oklahoma
Fields, grassland, moist places in canyons and along riverbanks
Thinly ovate, 3 inches in length, at intervals along the stems
The five petals of centaurium calycosum flowers are 1.5 inches long, bright pink, and white at the base, from which project the yellow-tipped stamens. There are several flowers along the tall stalks, on separate, short stems. Leaves grow at widely-spaced intervals on the stem, mostly towards the base, and have an opposite arrangement. The plant grows in generally arid, low elevation areas is not particularly common, due in part for its requirement to be close to a water source.
